Just like in previous spyshots, the S-specific features are somewhat lacking, even though the model is probably quite close to production.

You'd like to assume that most differences are under the bonnet. Otherwise it looks much the same!

Its simply a test mule. The SQ2...assuming it gets released would take little development. The Q2 is based on the MQB chassis so the 2 TSI lump and drivetrain from the S3 will drop straight in.

All of the newer S cars have had near identical styling to the S-line model. I would expect a slightly different grill and rear diffuser only.
